IPC: H04B7/26
Filed: 2007-12-27
Abstract: A transmission device includes: means for performing inverse Fourier transform on a signal for which a reference signal and a data signal have been mapped on respective sub-carriers; and means for radio-transmitting a transmission signal. A total power assigned for a signal which is transmitted in a certain time slot is maintained at the same level as the total power assigned for a signal which is transmitted in another time slot. The power density of the reference signal per unit band is set greater than the power density of the data signal per unit band. Since the total transmission power in each time slot is maintained at a constant level, the power amplification efficiency can be maintained at a high level. Moreover, since the reference signal is transmitted with a higher intensity than the other signals, the channel estimation accuracy is also maintained at a high level.

Patent CA-2675582-A1 (CA)
Inventor: MOORE WILLIAM P
IPC: A01K15/04
Filed: 2008-01-17
Abstract: Described is an animal containment system for containing an animal within a boundary, for maximizing the animal's usable area within the boundary, for not discouraging the animal from returning to within the boundary in the event the animal moves beyond the boundary, and for doing so without utilizing an independent polarity indicator. The animal containment system determines whether the animal is within the boundary or beyond the boundary by considering the polarity of an activation signal the animal containment system transmits from the boundary and receives at the location of the animal. The animal containment system determines the polarity of the activation signal by modulating the signal such that the modulation indicates the polarity of the activation signal. The animal containment system achieves the above-discussed features by delivering a stimulus to the animal only when it traverses the boundary from within the boundary.

Abstract: Systems, methodologies, and devices are described that can facilitate bandwidth efficient non-coherent signaling for uplink control channel transmissions. A communication device (e.g., a mobile device, base station) can be configured to utilize or generate a set of complex orthogonal codewords to facilitate transmission of control channel information using non-coherent signaling in a bandwidth efficient manner. A complex orthogonal codeword set can comprise a first subset of codewords where such codewords have a desirable cross-correlation property and another subset(s) of codewords that can include expurgated codewords, where the expurgated codewords can include discarded codewords and/or codeword pairs that produce a worst-case cross-correlation property. The codeword set and subsets are determined based at least in part on a predefined codeword criterion. A portion of the discarded codewords can be used for other purposes, such as erasure decoding, interference-level estimation, and/or multi-mode control channel operation.

Abstract: A system and method are provided for removing quadrature imbalance errors in received data. The method accepts an unbiased training sequence in a quadrature demodulation receiver. An unbiased training sequence has a uniform accumulated power evenly distributed in a complex plane, and includes predetermined reference signals (p) at frequency +f and predetermined mirror signals (pm) at frequency -f. The unbiased training sequence is processed, generating a sequence of processed symbols (y) at frequency +f, representing complex plane information in the unbiased training sequence. Each processed symbol (y) is multiplied by the mirror signal (pm), and an unbiased quadrature imbalance estimate B m is obtained at frequency (-f). Using quadrature imbalance estimates, channel estimates, and processed symbols, an imbalance-corrected symbol can be generated.

Title: Method for producing lithium vanadium polyanion powders for batteries
Inventor: LATIMER EDWARD G
IPC: C01G45/00
Filed: 2008-06-05
Abstract: A process for producing a cathode powder for making lithium ion batteries wherein the powder comprises lithium, vanadium and a polyanion. The process includes forming a solution-suspension of the precursors, including vanadium pentoxide, with a reducing agent, a solvent, and a carbon-residue-forming material. The reducing agent reduces the vanadium in vanadium pentoxide from V5+ to V3+. The solution-suspension is heated in inert environment to drive synthesis of the LVP so the carbon-residue-forming material is oxidized and precipitates, forming CCLVP. Liquids are separated from solids and the dry powder is heated to drive crystallization of the product. The product retains small particle size, includes carbon in the LVP for conductivity, and is created with low cost precursors and with no need to reduce the product size for use in batteries. Addition of carbon black, graphite or other form of carbon is unnecessary to provide the conductivity required for use in batteries.

Abstract: A system performs production optimization for oilfields using a mixed--integer nonlinear programming (MINLP) model. The system uses an offline--online approach to model a network of interdependent wells in an online network simulator while modeling multiple interdependent variables that control performance as an offline MINLP problem. The offline model is based on production profiles established by assuming decoupled wells in the actual network of wells. In one example, an amount of lift-gas to inject and settings for subsurface chokes are optimized. An offline solver optimizes variables through the MINLP model. Offline results are used to prime the online network simulator. Iteration between the offline and online models results in a convergence, at which point values for the interdependent variables are communicated to the real-world oilfield to optimize hydrocarbon production.  Priming the online model with results from the offline model drastically reduces computational load over conventional techniques. Additional techniques anneal initial data starting points, smooth pressure differences, and adapt constraint values to further reduce computational intensity.
